Definitions

  • the invention relates to a mixer assembly with a surrounding filter element, a storage space with a mixer assembly, a vehicle with a storage space and a method for installing a mixer assembly.
  • the invention relates to a mixer assembly with a filter element which fluidly connects an intermediate space surrounding a mixing chamber with the surroundings of the mixer assembly, as well as a storage space with such a mixer assembly and an aircraft with such a storage space.
  • the invention also relates to a method for the rapid installation of a mixer assembly in an aircraft.
  • a mixing chamber for mixing fresh air with recirculation air is usually housed in the belly of the aircraft, where the recirculation air is sucked off directly and conveyed into the mixing chamber.
  • two suction lines, each with a filter element are arranged on the mixing chamber.
  • Figure 1 shows an example of a view of a conventional mixing chamber 20 with two symmetrically arranged suction lines 21, each of which has a filter element 22 attached to its ends.
  • the air cleaned by the filter elements 22 is guided to the lower region of the mixing chamber 20 via the suction lines 21. There it can be mixed with fresh air from fresh air lines 24. In the upper area, the mixed air is fed to the corresponding mixed air lines.
  • the mixed air can be fed into an aircraft cabin, a cockpit and / or a cargo hold.
  • the filter elements 22 are arranged in the space of the aircraft so that they are easily accessible on the one hand to facilitate replacement and on the other hand to receive recirculation air from both sides of the aircraft space in order to enable even and symmetrical recirculation air flow from the passenger cabin above.
  • US2015 / 064061 discloses a filter element and US 10023317 , WO2016 / 045582 JPH 06 316297 disclose mixer assemblies for aircraft.
  • the invention is based on the object of providing a compact mixer assembly. Furthermore, the invention is based on the object of a storage space and a To provide aircraft with such a mixer assembly and a method for simple installation of a mixer assembly.
  • This layered, onion-like structure results in a very compact mixer assembly.
  • the omission of separate suction lines, as in conventional systems, allows a compact mixer assembly.
  • the space between the mixing chamber wall and the casing takes on the function of thermal insulation of the mixing chamber. Thermal insulation from the surroundings of the mixing chamber is achieved solely through the two-shell structure, but also through the mostly warmer fluid that can flow through the intermediate space. It is therefore possible to dispense with additional insulating elements, as are necessary in conventional mixing chambers, so that the construction of the mixer assembly is also very compact.
  • the filter element can be detachably arranged on the mixer assembly.
  • the direct arrangement on an outside of the jacket enables a further reduction in the size of the mixer assembly.
  • the arrangement of the filter element on the casing and on its opening (s) provide effective soundproofing.
  • the external filter element absorbs sound both from the space in between from the mixing chamber, which means that no additional noise protection measures are required.
  • the mixer assembly can also comprise a multiplicity of filter elements.
  • the filter elements can cover the casing together without overlapping one another. Alternatively or additionally, the filter elements can overlap one another at least in sections and thus form a multi-layer filter element. Several thinner filter elements can be attached more easily, especially in difficult-to-access mixing chambers, while a single filter element can be attached more quickly.
  • the filter element can have a contour on a side facing the casing, which at least in sections corresponds to a contour of an outer side of the casing. This positive-locking arrangement of the filter element on the casing prevents air from flowing past the filter element into the space.
  • the filter element can have a sealing element on an outer edge of the filter element facing the casing, which sealing element rests against the casing. This also prevents flow around the filter element.
  • the mixer assembly can furthermore comprise a delivery device which is set up to deliver a fluid through the filter element into the intermediate space and out of the intermediate space into the mixing chamber.
  • the delivery device is dimensioned in such a way that it ensures a sufficient volume flow of fluid through the filter element in order to provide sufficient recirculation air to the mixing chamber.
  • the volume flow of the recirculation air can be regulated by the conveying device.
  • the mixer assembly can also comprise a multiplicity of delivery devices, each of which is set up to deliver a fluid through the filter element into the intermediate space and from the intermediate space into the mixing chamber.
  • the conveyor device is arranged in the intermediate space.
  • the delivery device can generate a volume flow within the space. If the space is closed with respect to the surroundings of the mixer assembly with the exception of the openings facing the filter element, fluid is sucked through the filter element into the space.
  • the fluid can be conveyed through the mixing chamber wall into the mixing chamber.
  • the mixing chamber wall can have one or more openings for this purpose, through which the fluid flows.
  • the conveying device is completely accommodated between the mixing chamber wall and the casing, with at least one of the openings in the mixing chamber wall and the casing being located on both sides of the conveying device (inlet side and outlet side).
  • the interspace, completely or at least a part thereof, is quasi formed by the interior of the conveying device, wherein the casing serves to hold the filter element or can also be omitted.
  • an effective filter cross-sectional area is necessary which is larger than an area of the conveying device cross-section in order to ensure trouble-free filtering of the fluid.
  • a check valve can also optionally be arranged on the outlet side of the delivery device and / or in / on the mixing chamber wall. This prevents fluid from flowing out of the mixing chamber into the intermediate space and / or the conveying device instead of flowing to the outlet of the mixing chamber.
  • the mixer assembly can further comprise a premixer which is fluidically coupled to the inlet of the mixing chamber.
  • the conveying device can convey the fluid from the intermediate space into the premixer.
  • the fluid can be combined with another fluid flow.
  • the premixer can have a removal opening in order to remove premixed fluid before it flows into the mixing chamber (e.g. for forwarding it to prioritized areas of the aircraft (e.g. the cockpit or air-consuming devices).
  • this can furthermore comprise a fresh air supply line which is fluidically coupled to the inlet of the mixing chamber.
  • the fresh air line can provide fresh air from an air conditioning pack (for example an aircraft air conditioning system).
  • the fresh air can then be mixed with the recirculation air in the mixing chamber, the ratio of the two air flows satisfying various parameters. These include only examples of temperature, humidity and minimum fresh air supply per passenger.
  • a storage space in a vehicle comprises a mixer assembly according to the first aspect or one of the configuration variants described.
  • the storage space can be a space in the belly of an aircraft, for example in the lower fuselage, at the wing roots and / or in the vicinity of an air conditioning pack of the aircraft.
  • the storage space has supply lines with recirculation air or is in some other way connected to an area of the aircraft (e.g. a passenger cabin) fluidically coupled (e.g. via DADO panels) in order to direct recirculation air into the storage space and then take it in (sucked in) through the filter element of the mixer assembly.
  • the storage space can furthermore comprise a partition which separates the storage space containing the mixer assembly from a cargo space.
  • the partition wall serves to seal off the cargo hold from other areas of the aircraft.
  • the partition can have at least one filter installation opening.
  • the filter element can be designed to be pushed through the filter installation opening and, in an end position, to fluidically connect the intermediate space to the surroundings of the mixer assembly and to fluidically seal the filter installation opening.
  • the partition and the mixer assembly are arranged relative to one another so that the filter element can be brought from the cargo hold into an installation position (end position) within the mixer assembly in which the filter element filters the recirculation air conveyed into the mixing chamber.
  • the filter element can also have a closing element that can be received in the filter installation opening at least in sections.
  • the closing element can have a section whose shape corresponds to the filter installation opening. This allows the filter element to completely close the filter installation opening. Either the closing element fits into the filter installation opening, with the closing element being flush with the partition (i.e. lying in one plane), or it completely covers the filter installation opening, with part of the closing element resting on the partition and thus protruding from it (viewed perpendicular to the partition plane ).
  • the filter element or the partition wall can have a sealing element in order to ensure a fluidic seal between the cargo space and the storage space.
  • a cargo hold must be sealed off from other areas of the aircraft so that no hazardous substances (smoke, gases, etc.) escape from the cargo hold and reach other areas (e.g. passenger cabin, cockpit, etc.).
  • the closing element has a locking device which is set up to lock the closing element on the partition in such a way that the filter element is fixed in its end position.
  • the closing element can also be held in the position in which it seals the filter installation opening and thus the cargo space.
  • a vehicle comprises a storage space according to the above aspect or one of the associated configuration variants.
  • the vehicle can be any vehicle equipped with a ventilation / air conditioning system with recirculation air mixture.
  • the vehicle can be an aircraft.
  • a method for producing a mixer assembly in an aircraft comprises the following steps: providing a mixing chamber which comprises a mixing chamber wall delimiting the mixing chamber; Attaching a casing which surrounds the mixing chamber wall at least in sections and delimits an intermediate space between the mixing chamber wall and the casing; Attaching a filter element to an outer side of the casing, the filter element fluidically connecting the intermediate space to an environment of the mixer assembly, and wherein the intermediate space is fluidically connected to the mixing chamber; Introducing the mixer assembly with attached casing and filter element into a storage space of the aircraft; and securing the mixer assembly in the storage space.
  • the sheathing can also be attached in a manufacturing step of the mixing chamber.
  • the mixing chamber wall and casing can be produced in one step. Injection processes, drawing processes, 3D printing processes or the like are suitable for this, whereby two parallel (or concentric) walls can be formed at the same time.
  • the method further comprises removing the filter element from the mixer assembly; and attaching a new filter element to the outside of the shell. These steps can be performed without removing any other part of the mixer assembly.
  • This replacement of the filter element usually has to take place at regular intervals and can be due to the arrangement the filter element on the mixing chamber can be carried out particularly quickly.
  • the filter element lying on the outside of the mixing chamber can be easily and quickly detached and replaced with a new filter element.
  • a mixer assembly with a mixing chamber wall and a casing surrounding the mixing chamber wall is described, a filter element fluidically connecting a space between the mixing chamber wall and the casing with the surroundings of the mixer assembly and the space being fluidically connected to the mixing chamber. Furthermore, a storage space with such a mixer assembly, a vehicle with such a storage space and a method for producing a mixer assembly are described.
  • FIG. 11 schematically shows a perspective view of a mixer assembly 100
  • Figure 4 shows a schematic cross section longitudinally through a mixer assembly 100
  • the mixer assembly 100 comprises a mixing chamber 110, which has at least one inlet 111 and at least one outlet 112 and a mixing chamber wall 113 that delimits the mixing chamber 110 in between.
  • the mixing chamber 110 is surrounded by both a casing 120 and a filter element 130.
  • the mixing chamber wall 113 is surrounded at least in sections by the casing 120, the casing 120 delimiting an intermediate space 121 between the mixing chamber wall 113 and the casing 120.

  • the filter element 130 applied on the outside of the casing 120 fluidly connects the intermediate space 121 with the surroundings of the mixer assembly 100.
  • the filter element 130 can rest on the casing 120 and thereby cover an opening 122 in the casing 120.

  • the filter element 130 has a contour 133 on the side facing the casing 120 (inside), which at least in sections corresponds to a contour of an outside of the casing 120. This makes it a firm concern of the filter element 130 on the casing 120, which in turn prevents a fluid from being sucked in between the filter element 130 and the casing 120 and thereby bypassing the filter element 130.
